How to transfer video to Sony PSP?

    As referred above, PSP system uses Memory Stick Duo to store games, music, videos, photos and other contents,
so its movies shall be saved to Memory Stick Duo for playback. For PSPs with firmware v3.30 or newer, users can transfer
 MP4 to the VIDEO folder. For older versions, a normal PSP movie should consist of a .MP4 and a .THM file,
named as M4Vxxxxx.MP4 and M4Vxxxxx.THM (xxxxx is the same 5 numbers in this pair of playable structure files,
and .THM is .MP4's thumbnail file which is not necessary to be transferred into PSP); users should put them
in the 100MNV01 folder.
Step 1 : import video into PSP memory card
Connect PSP's Memory Stick Duo card with computer, via PSP or card reader or memory stick adaptor as you like, and the card
directory is as below:
Memory Stick Duo root
│
├PSP
│
├MP_ROOT
│ ├100MNV01 (Put .MP4 & .THM files here)
│ ├100ANV01
│ └101ANV01
├MUSIC
├ISO
├PICTURE
└VIDEO (If your firmware is 3.30 or newer, moving MP4 here will be ok)
Step 2 : play converted video on PSP

Once the video is transferred successfully, go to menu VIDEO > Memory Stick, you can find and play
the video on PSP now.
